Things You'll Need:
- Paint (oil base)
- Primer (oil base)
- Roller brush
- Paint pan
- Tarp or painter's canvas
- Vinegar
- Water
-
Step 1
Use vinegar to wipe down the whole surface of the garage door. Wait until the vinegar dries, and then rinse off the door with water. The acid in the vinegar will remove the oils that protect the steel and will help the primer stick to the door.
-
Step 2
Spread out the painter's canvas or tarp below the garage door. Make sure that the tarp is covering the whole working area.
-
Step 3
Open the oil based primer and stir well. Pour the primer into the paint pan. Make sure the garage door is dry before applying any paint. Use the paint roller to apply even coats of primer on the garage door until completely covered.
-
Step 4
Give the primer a half an hour to an hour to dry completely. This could be faster depending on how hot the day is or how much direct sunlight the door is getting. An easy test to see if the paint is dry is to lightly touch your finger to it to see if any of it comes off. If not, then the primer is dry.

Step 5
Open the oil based exterior paint and stir well. Pour paint into paint pan. Apply an even coat of exterior paint to the door until it is completely covered. When the first coat of exterior paint dries, if you can still see the primer through it, then apply another even coat until the color is solid.
